TEC and ROTI Measurements from a New GPS Receiver at BOWEN University, Nigeria

Scintillation and total electron content (TEC) are the two major examples of top-side ionospheric parameters that recorded differently by most Global Positioning System (GPS) receivers. The new GPS sensor created Atmospheric Space Technology Research Associates (ASTRA), Cornell University, University Texas, Austin have capability to record scintillation TEC fluctuations simultaneously. Hence, Connected Autonomous Environment Sensor (CASES) from ASTRA is a software-defined receiver with dual frequency L1 C/A L2C codes for space-weather monitoring can be remotely programmed via an internet source. employs numerous novel techniques make it suitable studies compared other nearby receivers, such as different methods eliminating local clock effects, advanced triggering mechanism determining onset, data buffering permit observation prelude scintillation, data-bit prediction wipe-off robust tracking. Moreover, CASES hardware made up custom-built frequency, digital signal processor board, “single board computer” ARM microcontroller. We used newly installed at Bowen Iwo, Nigeria, investigate rate index (ROTI) around equatorial region. Measurements ROTI showed similar variation trends in monthly, seasonal, annual periods when measurements station, BJCO Cotonou, Benin Republic. looks promising scientific use only one operational Nigeria moment.
